Just upgraded to natty. This is the first time I turned on my computer to use it. It didn't show anything but my wallpaper. No side panel or taskbar. Just the wallpaper. Now, I sort of know what happened (I played around with the appearances a little).

*Can anyone give me the commands to open the login setting as well as appearance in order to change my settings to normal? *

Note: I didn't install anything. Just changed some settings to the login screen for it not to show up or something close to that.

I would love to show you all the evidence but I'm posting this via cell phone. Please help me! I know how to open terminal it's the programming I need help with. Thanks!

I had to figure out how to open compiz without anything but a desktop (create an icon on the desktop). Then reset the effects settings, for my desktop I have: In Desktop -> Desktop Wall, Expo, Unity Plugin, Viewport Switcher; Window Management -> All, but app switcher, put, shift switcher and ring switcher.

You can probably choose whatever you want for the other categories, but I can specify those too if need be.
